Application filed August 5, 1912, Serial No. 713,262. Renewed March 3,1916. Serial No. 82,001.

To all whom it may concern:

Beit known that I, ELMER M. COBB, of South Portland, in the county ofCumberland and State of Maine, have invented certain new and usefulImprovements in Magazines for Feeding and Storing Rivets, of which thefollowing is a specification.

My invention relates to a magazine adapted to be used for containing adefinite number of rivets and for delivering the same one at a time whenneeded. The magazine is designed particularly to be used in connectionwith a riveting machine which is to be the subject of a laterapplication but it is adapted to be used for other purposes or whereverit is desired to store and feed rivets or any similarly shaped articles.

The magazine is intended as a holder or container in which the rivetsmay be stored and shipped and put on the market for the use of saidmachine and at the same time it is designed to act as a feeding devicewhich may be applied to the machine delivering the rivets one at a timeto replace those used.

My invention may best be understood by reference to the accompanyingdrawing, in which is shown one form of magazine constructed according tomy invention.

In. the drawing, Figure 1 is a vertical section through the magazinetaken on the line a; 00 of Fig. 4:, Fig. 2 is a plan of the same withthe cover left ofi, Fig. 3 is a part elevation and part section on theline 3 11 of Fig. 4 with portions of the casing cut away to show thespiral guides, Fig. 4: is a plan of the bottom of the casing showing thechute in section on the line 50 m of Fig. 1, and Fig. 5 is a section onthe line 1 1 of Fig. 1.

Referring to the drawings. A represents a cylindrical casing in which isarranged a spiral guide which is adapted to support the rivets f ontheir sides and to form an inclined run-way by which they may roll fromtop to bottom.

As here shown, the spiral guide designated generally as B, is formed ofa spiral strip T-shaped in cross section with a stem portion or singleflange b horizontally disposed and the double flanged portion Z)vertical. The upper edge of the vertical. por tion 5 forms a spiralrun-way for the rivets and the lower portion forms a guide for the rivethead. The flange 12 fits in a spiral internal groove a formed on theinside of the casing and it also forms a guide or runway for the edge ofthe rivet head and in conjunction with the upper edge. of the flange 6supports the rivet in a horizontal position, the small end pointinginward.

The pitch of the spiral is such that the rivets will roll freely fromtop to bottom. A cover a is provided for the top of the cylinder andthis cover is provided with a flange, a portion of which is bent inwardat a to form a stop which abuts against the upper end of the spiral guile B. A base or bottom head a is provided with an outlet opening atplaced opposite the lower end of the spiral guide through which openingthe rivets drop as they reach the bottom of the guide. The cover a andthe bottom head a are preferably securely fastened to cylinder A.

A shut-off is provided by which the opening a may be closed when themagazine is being transported and rivets are not to be used.

As here shown, a shut-off platee is pivoted at the center of the bottomhead a (shown in dotted lines in Fig. 4:). One end is broadened out toform a shut-off for closing the narrow portion of the opening a and theopposite end is turned down to form an operating handle 6 which travelsin a slot 6 An upward extending flange or stop a on the shut-off 0serves as a guide for the rivet bodies when the rivets are dischargingand it also serves to close the lower end of the run-way when theopening a is closed to hold the rivets in place on the guides. Thecylinder is supported in an upright position by suitable means.

As here shown, the upright support is utilized to hold the cylindricalcasing together. The adjacent edges or flanges a of'the casing are bentoutward in a diverging position to form a tongue which fits within thestandard d. The standard d is triangular in section and forms with theflanges a a dove-tail connection whereby the cylinder may he slippedinto the standard from above. The cylinder is both held together andsupported in a vertical position by this locking arrangement.

The lower end d of the standard is enlarged and extended laterally toform a chute into which the rivet falls after it passes through theopening a and within which the rivet head loosely fits. The body of therivet projects through the slot or opening 03 This chute or guide may beextended and carried to the place where the rivets are to be deliveredas desired.

In using the device the magazine is filled with the rivets, and theshut-off is then closed. It is then attached to the support and theshut-off opened, allowing the rivets to run down through the chute. Themagazine forms a convenient package in which to supply the rivets to thetrade as it is only necessary to attach it to the machine and when emptythrow it away or return it to be refilled.

It may be used as a magazine or reservoir in any position where it isdesired to feed rivets or similarly shaped articles one at a time. Ithas considerable storage capacity and may be made as large in diameterand as long as desired.

I claim c 1. In a magazine for storing and feeding rivets and otherarticles of similar shape, the combination of a stationary, verticallydisposed cylindrical casing and a fixed spiral guide in said casingconstructed and arranged to support the rivets in a horizontal rollableposition on their sides.

2. In a magazine for storing and feeding rivets, the combination of astationary, vertically disposed cylindrical casing and a fixed spiralguide on the inner surface of said casing, said guide being T-shaped incross section and being placed to support the rivets on their sides.

3. In a magazine for storing and feeding rivets, the combination of astationary, vertically disposed cylindrical casing and a fixed spiralguide in said casing, said guide having a T-shaped cross section withthe stem portion horizontal, the edges of the vertical portion forming aspiral track for the bodies of the rivets to roll on and a spiral flangeto guide the rivet heads.

I. In a magazine for storing and feeding rivets, the combination of acylindrical casing having a spiral groove therein and a spiral guideT-shaped in cross section with the stem portion horizontal, the stemp0rtion fitting said spiral groove and being held thereby.

5. In a magazine for storing and feeding rivets, the combination of acylindrical casing, a spiral guide within said casing constructed andarranged to support the rivets in rollable position on their sides, thelower end of said casing having a discharge opening for said rivets anda shut-off for closing said discharge opening.

6. In a magazine for storing and feeding rivets, the combination of acylindrical casing having adjacent longitudinal edges bent outwarddivergently to form a dove-tail tongue, an upright support for saidcasing having a longitudinal recess into which said tongue may slide anda spiral guide within said casing constructed and arranged to supportthe rivets in a rollable position.

7. In a magazine for storing and feeding rivets, the combination of acylindrical casing having adjacent longitudinal edges bent outwarddivergently to form a dove-tail tongue and having a discharge opening inits lower end, and an upright support for said casing having alongitudinal recess into which said tongue may slide, the lower end ofsaid support being enlarged and extended beneath said opening to form achute to receive the discharged rivets.

8. A magazine for storing and feeding rivets including a cylindricalcasing and a spiral guide constructed and arranged to support rivetshorizontally on their shanks, said guide consisting of a flange verticalin cross section arranged spirally within said casing, the turns of thespiral being so close that the lower portion of the flange at any giventurn acts as a guide for the upper portion of the rivet head when therivet is on the next lower turn.

In testimony whereof I have affixed my signature, in presence of twoWitnesses.
